In it, players control either Phineas, Ferb, Agent P, or Alternate Candace as they infiltrate the lair of Alternate Doofenshmirtz to stop his reign of terror across the Tri-State Area. The gameplay is similar to that of another Phineas and Ferb online game, Transport-inators of Doooom!.

Story

In the 2nd Dimension, the Resistance finally corners Alternate Dr. Doofenshmirtz and tells him that they will not let him conquer the 1st Dimension, but Alternate Dr. Doofenshmirtz traps them and sends them to the mine. They manage to fight their way to the robots and finally escape by using the mine-carts.

Then The Resistance reach the Laboratory and they are informed by Major Monogram that Alternate Dr. Doofenshmirtz is using the Other-Dimension-Inator to transport his Norm Bots to invade the 1st Dimension. Monogram tells them to destroy the Other-Dimension-Inator immediately. They manage to reach the Other-Dimension-Inator and destroy it, escaping the ensuing explosion via blimp.

The game has 3 trophies in each level: Finish it in the fastest time, collect instrument music for the movie, and gears. However, when getting hit by the enemy will scatter 5 gears, making it difficult to the complete the gear trophy.

There are three types of power ups in the game: a magnet that attracts nearby gears or badges towards the player; a lightning bolt icon that turns the player invincible and allows them to instantly defeat any enemies they touch; and a red stop sign, which stops all of the robots from moving for a limited time.

Songs

The game features instrumental versions of a wide selection of songs from the movie and some of the songs from Transport-inators of Doooom!, most of which must be unlocked by finding the hidden CD in each of the game's 13 (including the tutorial) levels.

Even if levels 1-8 are cleared with Phineas-2 or Ferb-2, the cutscenes still show first-dimension Phineas and Ferb, and Agent P doesn't change at all after beating Level 8.

If the boys had started counting from when Alternate Doof was born, the number of days would be much more than 16,000 days; it is approximately equal 44 years, but seeing as he is 47 (Quietest Day Ever) the day count is around 17,000.

On Level 12 (the final level), where you have to destroy the giant boss Normbot, if you drop into a pool of orange/blue goo, you drop below it and end up surrounded with stars and all you can do is fly. The only way out of this glitch is to restart the level, unless you hit the checkpoint after the row of moving platforms.

At the start of the game Isabella-2 says Fireside Girls rather than Firestorm Girls.
